Evolution Aluminum Vacuum Valve Housing

Ossur® The VV03-006 Aluminum Vacuum Valve Housing fits into the AK Lamination Valve Housing and offers a more durable aluminum body specifically for transfemoral double wall definaitive sockets. The VV03-006 also holds the duckbill valve which creates a safety valve between the socket and any vacuum systems, so if the vacuum system fails the socket still works as an expulsion system.
